In the hotel.

  Professor Derry was on the phone with Nicholas Xiu. Their signal was completely through the channel that Nicholas Xiu had created himself and would not be detected by China.

  Professor Derry said, “I offered many temptations to Feng Xingshen, and he was very tempted. He also agreed to let me choose an exchange student, but when I mentioned Xue Xi, Feng Xingshen rejected it on the spot.”


  He frowned. “If Xue Xi is only a very talented student, I think Feng Xingshen will definitely not reject my choosing her. Could it be that he knows what’s special about Xue Xi?”


  Nicholas Xiu said, “Perhaps he knows, or perhaps…… he doesn’t dare to have any ideas about Xue Xi just because he wants to.”


  Professor Derry paused and suddenly understood. “Yes, that must be it! Then what should we do now?”


  Nicholas Xiu slowly said, “It’s fine. Work hard. If you can’t bring her back, you can seek to understand her more and see if she’s the person I’ve been looking for.”


  Professor Derry replied, “Okay, Your Excellency.”


  Country M.

  Nicholas Xiu looked at the exquisite computer in front of him and cut off the newly built passageway. After checking, he saw that there were no signs of being attacked.

  It seemed that Xiang Huai did not realize that he’d been on the phone.

  Since that was the case…… He decided to go to Huaxia University to see if he could obtain some news about Xue Xi.

  At this thought, Nicholas Xiu placed his hands on the keyboard and started typing……

  At this moment, in the school’s server room.

  In a huge room that was 200 square meters, there were many servers, firewalls, and other equipment. All of them were buzzing.

  Many seniors from the Computer Department were busy.

  “The firewall loophole has been discovered and is being repaired quickly!”


  “The new algorithm is unsuitable. What should we do?”


  “Have you not thought of an optimization plan yet?”


  “No! But we invited a few people from the Math Department to see if we can get any inspiration from them!”


  “Where’s Yu Da? Why isn’t he here yet?!”


  “Some people said that he got into a fight and was taken away by the student council. They probably haven’t finished interviewing him yet!”


  “Aren’t those such small matters? Call the student council and ask Yu Da to hurry over. Can’t you tell what’s more important?”


  “Okay.”


  Following the buzzing sound, everyone in the room was busy but not in a mess. They each had their own duties. There was no choice. The school’s firewall was suddenly attacked. Fortunately, it was discovered in time. Otherwise, the school would have lost all its secrets.

  After the discovery, the firewall had been updating and optimizing, but it could not stop the other party’s attacks.

  “What should I do? I can’t take it anymore!”


  “Me too! Why isn’t Yu Da back yet?!”


  This was what Xue Xi and Xie Yingying saw when they arrived.

  The entire room was in a mess and they could barely hear what they were saying. The only thing they could understand was that they were shouting for Yu Da.

  As everyone was busy, no one greeted them. Only a senior saw the two of them and hurriedly asked, “Are you from the Math Department?”


  Xie Yingying nodded. “Yes!”


  “Which year are you in? Have you finished learning linear algebra?”


  “We’re still in our first year.”


  The senior could not help but ask, “What are you doing here?”


  He was very anxious and wanted to say something, but when he saw Xie Yingying and Xue Xi’s beautiful faces, he suppressed the anxiety in his heart. “Forget it. Since you’re already here, you guys should help us! Come, let’s print these papers!”


  Just as Xie Yingying was about to say something, the senior took out his phone and called the student council. “Our firewalls can’t hold on any longer. Are you still not letting him go? Do you know what’s going on? If you don’t let him go, Huaxia University’s reputation will crumble! Hurry and let Yu Da come back! If this drags on, will you guys take responsibility?”


  The president of the Student Union could only say helplessly, “Alright, alright. We’ll let him go for now. When you guys are done with your work, we’ll get someone to investigate.”


  The senior heaved a sigh of relief.

  After hanging up, he turned to look at Xie Yingying. Seeing that she was still standing there, he said, “Why are you still standing there? Can’t you print it?”


  Only then did Xie Yingying return to her senses. “Yes, yes. I’ll go right now!”


  She grabbed Xue Xi and took the piece of paper. She ran to the printer beside her and copied it out. When she was done, she went to give it to the senior again. The senior pointed at the door and said, “Go over there. When the third- and fourth-year seniors arrive, let them see if there are any optimization algorithms!”


  “Whoever has a good idea, bring it to me immediately!”


  Xie Yingying hurriedly nodded and dragged Xue Xi to the door.

  Xue Xi: “.……”


  She looked at Xie Yingying and extended her hand. “Give me one.”


  “Oh,” Xie Yingying replied. She passed her a piece of paper and asked, “Sister Xi, are you alright?”


  Just as she said this, a third-year student came over. Xie Yingying hurriedly passed the paper to the other party according to her senior’s instructions and conveyed the request.

  Someone wanted to invade Huaxia University. This was an invisible war on the Internet!

  Everyone from Huaxia University had to protect the school’s honor!

  Hence, everyone became nervous.

  The seniors who came ran to the side to calculate and optimize the solution to see if there were better algorithms.

  In the room, someone continued shouting, “Where’s Yu Da? I can’t take it anymore!”


  “My side is also about to be defeated! Why isn’t Yu Da here yet? Is he a turtle? Is he crawling over?”


  “Have you reached it?”


  Voices calling “Yu Da,” “Yu Da” floated above the computer room. Xue Xi’s head hurt as she heard them.

  She held her breath and focused on the algorithm in her hand.

  This should be an Optimization plan for the firewall, but it was actually useless against the current attack. The Optimization of the firewall could only be done after the attack and defense were over.

  This was a battle!

  She looked into the room.

  All the seniors and the teachers on duty in the computer room were working hard. They were staring at the screen and typing something on the keyboard.

  There was no scheming in the room. At this moment, there was only one thought, and that was to unite against outsiders!

  This passion infected Xue Xi.

  Xue Xi, who had always been uninvolved, walked to the senior’s side and said, “Senior.”


  The senior turned around. When he saw that it was her, he asked, “What’s wrong? Did anyone calculate the optimization plan?”


  Xue Xi nodded. “Yes.”


  The senior’s eyes lit up. “Who is it? Hurry up and hand over the proposal!”


  Xue Xi passed the paper to him.

  The senior took a look and flipped through it before saying, “Huh? Where’s the optimization plan?”


  Xue Xi pointed at her head. “Here.”


  The senior was stunned.

  Xue Xi said domineeringly, “Let me do it.”
